Noxious Weeds Program

Orange HawkweedISDA is responsible for administration of the State Noxious Weed Law. The State Weed Coordinator and the other program staff provide support, training, and organizational assistance to the counties and Cooperative Weed Management Areas throughout the state.

A Cooperative Weed Management Area (CWMA) is a distinguishable hydrologic, vegetative, or geographic zone based upon geography, weed infestations, climatic or human-use patterns.  CWMAs are formed when the landowners and land managers of a given area come together and agree to work cooperatively to control weeds.

Purple LoosestrifeIdaho has over 30 CWMA's covering 87 percent of the state. These CWMA's participate in the ISDA cost-share program, which assist the local agencies in the fight against noxious weeds.

Staff also represents the director and the department on the Idaho Weed Coordinating Committee and various other weed-related task forces, associations, and committees.
